Becky, talk in the auditorium

Becky is a high school sophomore.

Becky was in the auditorium, where all second-graders would receive a talk.

The talk would last about two hours, if the people in charge did not extend themselves talking too much.

However, it was still more than an hour when Becky felt a strong urge to shit.

Becky knew that students were forbidden to leave the talk before it ended, unless it was for an emergency. And she was sure teachers wouldn't consider "the need to shit" an emergency.

Becky looked towards the exit of the auditorium, which was behind her and saw that there was no teacher near the door.

Becky could take that opportunity to get out and go to the bathroom.
